Updating Through EOL Versions

If you currently use a WHMCS version that is past its End of Life (EOL) date, we recommend that you update WHMCS as soon as possible. We always recommend that you update WHMCS regularly and remain on a supported WHMCS version. This ensures that you receive all bug fixes and security updates and allows WHMCS Technical Support to easily assist you with problems.

We currently support the following versions of WHMCS:

WHMCS VersionCurrent TierRelease NotesAnticipated End-of-Life Date
WHMCS 8.10General Availability8.10 Release NotesApril 30, 2025
WHMCS 8.9Long-Term Support8.9 Release NotesJanuary 31, 2025
WHMCS 8.8Long-Term Support8.8 Release NotesAugust 31, 2024

These releases are in the Active Development stage of our development cycle. All prior versions have reached End-of-Life (EOL) and we no longer maintain them or release updates for them, regardless of the reason. If you currently use an EOL version of WHMCS, we recommend updating to a supported version as soon as possible.

Preparing to Update from an EOL Version

Whenever you update WHMCS, we recommend that you perform steps first to prepare for a successful update. This includes:

For steps and more information and recommendations, see Prepare to Update WHMCS.

EOL Version System Requirements

When you update through multiple versions, make sure that you meet the system requirements for each intermediate version. You may need to stop between versions in order to update for new requirements.

  • If you will use the Automatic Updater tool at Utilities > Update WHMCS, make sure that you meet our Automatic Updater requirements.
  • We only document selected information from WHMCS 7.10 and earlier, in order to facilitate updating from very old versions. If you do not see requirements for all of the necessary versions for your update or if you need additional information, contact WHMCS Technical Support.

Updating to a Supported Version

After you have ensured compatibility, the update process will resemble any other WHMCS update across multiple versions.

When you are ready to perform the update, you can choose between several update methods:

Update MethodDescription
Automatic UpdaterGo to Utilities > Update WHMCS to check for and perform updates. This feature downloads, validates, and extracts the new files and updates the database in one process.
We strongly recommend this method.
Command Line (Manual)Use the included install.php script to update WHMCS. This requires manually staging the necessary update files before running the PHP script.
We only recommend this method for advanced users.
Browser (Manual)Go to example.com/whmcs/install/install.php, where example.com is the domain for your WHMCS installation, and follow the displayed prompts to update WHMCS. This requires manually uploading the files to your WHMCS installation.

After the update finishes, check to ensure that WHMCS is working properly. We recommend testing all of the important features and functions in WHMCS, like logging in as a client and as an admin, viewing products, submitting support tickets, and placing new orders.
